-Creative Commons Legal Code
-
-CC0 1.0 Universal CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES
-NOT PROVIDE LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE
-AN ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS INFORMATION
-ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES REGARDING THE USE
-OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED HEREUNDER, AND DISCLAIMS
-LIABILITY FOR DAMAGES RESULTING FROM THE USE OF THIS DOCUMENT OR THE INFORMATION
-OR WORKS PROVIDED HEREUNDER.
-
-Statement of Purpose
-
-The laws of most jurisdictions throughout the world automatically confer exclusive
-Copyright and Related Rights (defined below) upon the creator and subsequent
-owner(s) (each and all, an "owner") of an original work of authorship and/or
-a database (each, a "Work").
-
-Certain owners wish to permanently relinquish those rights to a Work for the
-purpose of contributing to a commons of creative, cultural and scientific
-works ("Commons") that the public can reliably and without fear of later claims
-of infringement build upon, modify, incorporate in other works, reuse and
-redistribute as freely as possible in any form whatsoever and for any purposes,
-including without limitation commercial purposes. These owners may contribute
-to the Commons to promote the ideal of a free culture and the further production
-of creative, cultural and scientific works, or to gain reputation or greater
-distribution for their Work in part through the use and efforts of others.
-
-For these and/or other purposes and motivations, and without any expectation
-of additional consideration or compensation, the person associating CC0 with
-a Work (the "Affirmer"), to the extent that he or she is an owner of Copyright
-and Related Rights in the Work, voluntarily elects to apply CC0 to the Work
-and publicly distribute the Work under its terms, with knowledge of his or
-her Copyright and Related Rights in the Work and the meaning and intended
-legal effect of CC0 on those rights.
-
-1. Copyright and Related Rights. A Work made available under CC0 may be protected
-by copyright and related or neighboring rights ("Copyright and Related Rights").
-Copyright and Related Rights include, but are not limited to, the following:
-
-i. the right to reproduce, adapt, distribute, perform, display, communicate,
-and translate a Work;
-
-      ii. moral rights retained by the original author(s) and/or performer(s);
-
-iii. publicity and privacy rights pertaining to a person's image or likeness
-depicted in a Work;
-
-iv. rights protecting against unfair competition in regards to a Work, subject
-to the limitations in paragraph 4(a), below;
-
-v. rights protecting the extraction, dissemination, use and reuse of data
-in a Work;
-
-vi. database rights (such as those arising under Directive 96/9/EC of the
-European Parliament and of the Council of 11 March 1996 on the legal protection
-of databases, and under any national implementation thereof, including any
-amended or successor version of such directive); and
-
-vii. other similar, equivalent or corresponding rights throughout the world
-based on applicable law or treaty, and any national implementations thereof.
-
-2. Waiver. To the greatest extent permitted by, but not in contravention of,
-applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and
-unconditionally waives, abandons, and surrenders all of Affirmer's Copyright
-and Related Rights and associated claims and causes of action, whether now
-known or unknown (including existing as well as future claims and causes of
-action), in the Work (i) in all territories worldwide, (ii) for the maximum
-duration provided by applicable law or treaty (including future time extensions),
-(iii) in any current or future medium and for any number of copies, and (iv)
-for any purpose whatsoever, including without limitation commercial, advertising
-or promotional purposes (the "Waiver"). Affirmer makes the Waiver for the
-benefit of each member of the public at large and to the detriment of Affirmer's
-heirs and successors, fully intending that such Waiver shall not be subject
-to revocation, rescission, cancellation, termination, or any other legal or
-equitable action to disrupt the quiet enjoyment of the Work by the public
-as contemplated by Affirmer's express Statement of Purpose.
-
-3. Public License Fallback. Should any part of the Waiver for any reason be
-judged legally invalid or ineffective under applicable law, then the Waiver
-shall be preserved to the maximum extent permitted taking into account Affirmer's
-express Statement of Purpose. In addition, to the extent the Waiver is so
-judged Affirmer hereby grants to each affected person a royalty-free, non
-transferable, non sublicensable, non exclusive, irrevocable and unconditional
-license to exercise Affirmer's Copyright and Related Rights in the Work (i)
-in all territories worldwide, (ii) for the maximum duration provided by applicable
-law or treaty (including future time extensions), (iii) in any current or
-future medium and for any number of copies, and (iv) for any purpose whatsoever,
-including without limitation commercial, advertising or promotional purposes
-(the "License"). The License shall be deemed effective as of the date CC0
-was applied by Affirmer to the Work. Should any part of the License for any
-reason be judged legally invalid or ineffective under applicable law, such
-partial invalidity or ineffectiveness shall not invalidate the remainder of
-the License, and in such case Affirmer hereby affirms that he or she will
-not (i) exercise any of his or her remaining Copyright and Related Rights
-in the Work or (ii) assert any associated claims and causes of action with
-respect to the Work, in either case contrary to Affirmer's express Statement
-of Purpose.
-
-   4. Limitations and Disclaimers.
-
-a. No trademark or patent rights held by Affirmer are waived, abandoned, surrendered,
-licensed or otherwise affected by this document.
-
-b. Affirmer offers the Work as-is and makes no representations or warranties
-of any kind concerning the Work, express, implied, statutory or otherwise,
-including without limitation warranties of title, merchantability, fitness
-for a particular purpose, non infringement, or the absence of latent or other
-defects, accuracy, or the present or absence of errors, whether or not discoverable,
-all to the greatest extent permissible under applicable law.
-
-c. Affirmer disclaims responsibility for clearing rights of other persons
-that may apply to the Work or any use thereof, including without limitation
-any person's Copyright and Related Rights in the Work. Further, Affirmer disclaims
-responsibility for obtaining any necessary consents, permissions or other
-rights required for any use of the Work.
-
-d. Affirmer understands and acknowledges that Creative Commons is not a party
-to this document and has no duty or obligation with respect to this CC0 or
-use of the Work.
